General Description
AAT6950 integrates four H-bridge channels and a photo sensor driving transistor to provide highly efficient motor-driving solution for digital still cameras. The four channels include one constant-current/full-on drive H-bridge channel and three full-on drive H-bridge channels. The AAT6950 is capable of driving up to four motors such as shutter, AF, ZOOM, and AE motors according to the control signal generated by CPU. The AAT6950 also features fault protection such as UVLO and thermal Shutdown.
